Title: Improvements in fluid-control valves
IPC: F16K1/14
Filed: 1964-05-15
Abstract: 1,063,454. Valves. CONSOLIDATED ELECTRODYNAMICS CORPORATION. May 15, 1964 [May 23, 1963], No. 20250/64. Heading F2V. A valve 1, Fig. 1 (not shown), comprises a casing (10) having an inlet (17) and outlet (18) connecting with a chamber (12), a ball (16) disposed in the chamber, an actuator (14) for carrying the ball which is movable axially of the chamber (12) into a position in which the ball lies opposite a valve seat (24), and a member (31, (50) operable to displace the actuator laterally from this position to cause it to urge the ball into contact with the seat (24) in a direction substantially normal to the valve seat. The member (31) has a cam surface (50) and is secured to the casing (10) so as to extend upwardly through a bore (30) in the bottom of the actuator (14). Bore (30) has a cam surface (51) which co-operates with the surface (50), in the final downward movement of the actuator, to effect a pivoting movement of the actuator (14) about an upper extent of a valve seat (21). Prior to this final movement the ball (16) is moved towards the seat (24) by contact with the upper tip of the member (31) and with cam surfaces (42), 43). The actuator (14) has surfaces (33) to support the ball in the open position of the valve, which position is effected by upward movement of the actuator. The ball (16) may close on to the upstream seat (23), instead of the seat (24). The cam surface (50) may be planar and disposed on the side of the member (31) facing the seat (24).

Title: Process for improving dimensional stability of tensilized polyester film
IPC: B29C55/12
Filed: 1967-05-02
Abstract: 1,117,904. Polyester films. E. I. DU PONT DE NEMOURS & CO. 2 May, 1967 [3 May, 1966], No. 20274/67. Heading B5B. A process for improving the thermal dimensional stability of asymmetrically biaxially oriented linear polyester film by asymmetrically biaxially orienting the film as by stretching and thereafter heat-setting at an elevated temperature is characterized by heat-setting in two successive stages with the temperature in the first stage being within the range of from 150‹ to 250‹ C., and the temperature in the second stage being at least 5‹ C. below the temperature in the first stage, but above the second order of transition temperature for the film. Preferably, the temperature in the second stage is at least 10‹ C. below the temperature in the first stage. The operable maximum temperature difference is a function of the maximum operable temperature of the first stage and the minimum operable temperature of the second stage. The first stage heat-set is accomplished in the range of 150‹ to 250‹ C., the maximum temperature being approximately 5‹ to 10‹C. below the melting point for polyethylene terephthalate film and for copolyesters of ethylene terephthalate, containing isophthalic or other dibasic acids. The final heat-setting is accomplished at a temperature above the second order transistion temperature. This final heatsetting temperature varies with the molecular weight of the polymer, and with the nature of the polyester, i.e. polyethylene terephthalate or its copolyesters; for polyethylene terephthalate the minimum temperature has been found to be about 80‹ C. Temperatures below 80‹ C. are undesirable, especially where it is desired to impart a small degree of relaxation in the latter stage, e.g. in the longitudinal direction between the fast rolls and the quench rolls following heat-setting, suitably between the second heatset and quench. Examples are given.

Patent GB-933208-A (GB)
Title: Counter
IPC: G06M1/16
Filed: 1962-05-28
Abstract: 933,208. Weighing apparatus. TOLEDO SCALE CORPORATION. May 28, 1962 [July 13, 1961], No. 20407/62. Class 143. [Also in Group XIX] In a counter, especially for use in a weighing machine, the gear ratio between the first and second numeral wheels can assume one or other of two values according to whether the counter is operating at high or low speed. When a load is applied to or removed from a weighing machine a pair of resistance wire strain gauge bridges 202, Fig. 1, is unbalanced and a servomotor 214 drives the slider of a potentiometer 208 to restore the balance. The motor also drives a counter, Fig. 3, with numeral wheels 5-9, through a belt 29. Initially, the movement is rapid and a clutch 37, 39 engages to cause the units and tens wheels 5, 6 to move as one. The clutch disc 37 is pinned to shaft 20 to drive the potentiometer via gearing 22, 25 at a high speed. As balance is approached, however, solenoid 30 deenergizes to uncouple 37, 39 and engage cam follower 55, Fig. 9, with cam 52 driven by the tens wheel. As the cam follower reaches a low point on the cam it locks gear 46 and internal toothed gear 44 so that planet wheel 43 secured to cam disc 37 travels round the gear 44 so providing a 10: 1 reduction in the drive to the potentiometer. Simultaneously the 1: 1 ratio between the numeral and tens wheels is broken so that normal transfer is effected by mutilated pinion 82. The numeral wheels are provided with stepped cams for control of printing (Fig. 7, not shown). Excessive loads. The potentiometer has a range of 1000 lbs. If this load is exceeded a pin 97, Fig. 9, opens switches 100, 101 to cause motor 105 to adjust a selector 316, Fig. 2, so adding an increment of voltage to the potentiometer. The motor also drives a belt 108, Fig. 3, to advance the thousands wheel 8. Successive increments may be added up to a limit of 10,000 lbs. Short of the absolute limit the potentiometer finds a balance which is indicated on the counter, the pin 97 being thenclear of the limit switches. At the ultimate. limit switches 134, 135 are closed to give an alarm. In unloading pin 97 operates switches 102, 103 to perform the reverse process.

Abstract: 460,231. Milling-machines. HERBERT, Sm A., LLOYD, A. H., and MACLAREN, G. W. July 24, 1935, No. 21018. [Class 83 (iii)]- A milling or like machine having a table 12 which may be traversed either manually from a handle 15 or by power by means of a drop worm 17 coacting with a wheel 16 on the feed screw 13 has means coacting with projections 33, 36 on the table for engaging opposite ends of a pivoted member 21 connected to the worm box so that the worm mav be moved . positively into and out of driving position responsively to the table position. The worm box 18 is pivoted at 19 and carries a spring pressed plunger 29 coacting with a latch 25 which is loose on the shaft 20 carrying the pivoted member 21. The shaft 20 also carries a forked member 23 engaging, with lost motion, a projection 24 on the worm box. For manual engagement of the power feed. a handle 22 on the pivoted member is raised thus taking up the lost motion of the fork and then causing a projection 31 on the latch to engage under the projection 32 on the box to maintain the engagement. Reverse movement of the hand lever disengages the latch and allows the worm box to fall under gravity. For automatic actuation, the normal feed handle 15 may first be used to bring the work almost up to the tool, at which point the dog 36 engages a plunger 35 to pivot the member 21 and engage the power feed. After a predetermined traverse the second dog 33 engages another plunger 34 at the opposite end of the member 21 so as positively to disengage the feed. The dogs 33, 36 are in different longitudinal planes. A second set of dogs may be employed for power traversing in the opposite direction.
